Actually, Darwin enraged creationists by insisting that if "primitive" people were brought to England, they would be just like Englishmen in a few generations. Today, it's hard to find a racist evolutionist, since evolutionary theory shows that there are no biological human races.
However, ICR co-founder Henry Morris into the 1990s, was continuing to insist on the supposed intellectual and spiritual inferiority of blacks, and another of his co-founders, William Tinkel, was an enthusiastic eugenist. So where the Nazis.
Darwinists like Morgan and Punnett showed that eugenic beliefs were not only morally wrong (Darwin called it an "overwhelming evil") but scientifically unsupportable.
This is one of the major differences between creationism and science. Not to say all creationists are racists; today, most of them are not. Even in Darwn's time, a few important creationists like Samuel Wilberforce agreed with him on the question of slavery and racism.
But it's troubling that so many founders of YE creationism were racists.
